Classic San Diego canyon landscape with river rocks on a partly shaded trail. The far eastern part of the trail includes a steep sandstone portion with deep grooves. Not quite a sandstone slot canyon (at least not yet), but beautiful, unspoiled, and definitely unexpected. Minus one star for constant road noise from the 52 and for general proximity to the freeway. Climbing down the sandstone part of the trail, I felt almost awkwardly watched by drivers getting on the 805 south from the 52. But it is what it is; the freeways aren’t going anywhere anytime soon, and I hope the park isn’t either. Perfect for getting your nature fix without leaving the city.
